Null and Alternative Hypotheses

For each of the following pair of null and alternative hypotheses, determine whether the pair would be appropriate for a hypothesis test. If a pair is deemed inappropriate, explain why.

a. Ho: mu/10, H1: mu < 10
b. Ho: mu = 30, H1: mu &#8800; 30
c. Ho: mu > 90, H1: mu <= 90
d. Ho: mu <= 75, H1:mu <= 85
e. Ho: x-bar = 15, H1:x-bar < 15
f. Ho: x-bar/58, H1: x-bar &#8800; 58
